It is 741. After conquering a continent for the Merovingian kings, only one thing stands between Charles Martel and the throne - he's dying. Charles cobbles together a plan to divide the kingdom among his three sons, betroth his daughter to a Lombard prince, and keep the Church unified behind them through his friend Bishop Boniface. Despite his best efforts, the only thing to reign after Charles's death is chaos. His daughter has no intention of marrying anyone, let alone a Lombard prince. His two eldest sons question the rights of their younger pagan stepbrother, and the Church demands a steep price for their support. Son battles son, Christianity battles paganism, and Charles's daughter flees his court for an enemy's love. Based on a true story, Anvil of God is a whirlwind of love, honor, sacrifice, and betrayal that follows a bereaved family's relentless quest for power and destiny.
